Critical Point, Surge Point, Yield Point, Aniline Point, Triple Point, Triple Point Of Water, Melting Point, Auto Ignition Point?

Hare, we want to know about Critical Point, Surge Point, Yield Point, Aniline Point, Triple Point, Triple Point Of Water, Melting Point, Auto Ignition Point, etc. Which are the most important, in Ammonia Process, Basic Process, Chemical Engineering, Chemical Process Technology, Chemical Industries, Lubricant Manufacturing, Manufacturing Industries, Oil and Gas, Petrochemicals, Power Generation plants, etc.

# Critical Point:-

A point on a phase diagram at which both the liquid and gas phases of a substance have the same density, and are therefore indistinguishable.

# Surge point:-

(For Rotating Equipments), the peak point at the Performance Curve of the Centrifugal Compressors where the flow reversed back through the compressors blades.

# Yield point:-

In mechanical engineering, the load at which a solid material is being stretched begins to flow, or change shape permanently.

# Aniline point:-

The lowest temperature at which aniline and a solvent (such as gasoline) are completely miscible and which serves as an indication of the type of hydrocarbons present in the solvent, the content of aromatics being higher according to as the temperature is lower.

# Triple Point:-

The temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium.

# Triple Point Of Water:-

The temperature and pressure at which the three phases (vapor, liquid, and ice) of water, coexist in thermodynamic equilibrium. The Triple Point Of Water is 0.01°C /  273.16K / 32.01°F temperature and 4.58 mm of mercury.

# Melting “ Liquification “ Point:-

The temperature at which it changes the state of the material from solid to liquid at atmospheric pressure.
